Whemo Sulfosulfuron 75% + Metsulfuron Methyl 5% WG is a post-emergent, selective herbicide used to control weeds like Phalaris minor and broadleaf weeds in wheat crops. It works by inhibiting amino acid biosynthesis in weeds, providing a dual action through the combination of its two active ingredients. The "WG" indicates it is a water-dispersible granule that is applied by dissolving it in water and spraying.
